The Siberian tiger is the largest cat species and lives in forests and grasslands of Russia and China. It can grow up to 13 feet long and weigh over 700 pounds. Siberian tigers have thick fur to survive temperatures as low as 70 degrees below zero. They are skilled hunters that stalk and ambush prey like deer, pigs, and bears. With fewer than 200 remaining in the wild, Siberian tigers are endangered due to habitat loss and poaching, and conservation efforts are needed to prevent their extinction.
